A partition 5 extends longitudinally through the center of the tub, thus dividing the tub into two opposite channels. The breaker roll is mounted in one of the channels only and thus'acts in the operation of the breaker to cause all the material to circulate in the tank and to pass repeatedly under the breaker blades which are of heavy construction and dull and do not materially ail'ect the fibrous material, but act to break up and reduce the non'iibrous material to the required fineness. The breaker may be operated from any suitable source of power by means of the belt connection 6.

i The heaters E 11] illustrated in Figs. 1 and 2 correspond generally in construction to the breaker H, consistin r as here shown of the tub 7, beater roll 8, dividing partition 9 and belt connection 10. Beater blades are arranged in the roll 8 suhstantiall in the same manner as in the breaker ml 2, except that the blades are relatively sharp and have a direct grinding action on the stock, thus acting to reduce the fibrous 'terial as well as the non-fibrous by the continuous grinding thereof.

The special feature shown in a con sists of a device known in pulp manufacture ing a perforated hack-fall plate. The device of itself constitutes the subject inattcro'f U. S. Letters Patent No. 1,271,426, i sued .to lirovvnell Buehler, Jul 2nd, 1918. lhis invention consists of a per orated Plate 11- arranged transversely in the tank ot the beater or breaker and cooperating with the heater roll to effect the reduction of the stock to the required state of fineness to permit the same to pass through the apertures in the back-fall plate. Thus with the coutinw ous operation of the beater the finished stocir. will be constantly flowing through the backfall plate, and may then he delivered into any suitable receptacle t'or'finished pulp.

The )ulp thickener F as best shown in Fig. 4, 15 also of the usual construction, 0011- sisting of the tank 12, cylinder meld .13, couch roll i l, and scraper 15; the material being discharged from the scraper into a hopper 16 in which an agitator of any suit able construction may be operated through the connection 17 to maintain even mixture of the stock as it is transferred from the hopper to a stufi' chest or other suitable rece tacle for the finished pulp.

he disintegrator G, as shown, consists of a rotatable tank in which a longitudinal, spiral partition 18 is arranged. The tank may be charged in any suitable manner with hot water, or may" be charged with cold Water, means being then provided to heat the water, together avith the. raw stock in. the tank, to effect disintegration of the re-- 'ducible material as it follows the spiral course through the tank.

The sifter B may he of any suitahle construction of rotary or reciprocating sieves or screens which will act to separate the tine dirt and dust from the raw stock, the present showing of the device being conventional only for illustrative purposes.

The pump G, also here shown conventionelimination of dust and line dirt from the stock loefore the same is delivered into the disintegrator C.

It is here noted that for certain grades of pulp made from dam stock, or more esec1ail* for certain finisned urcducts to he made of it. sitting or screening of the stock will not e required as all reducible material may he used. The dieintegrator C will then be charged with the stock direct from the carrier A or other suitahle means of conveying the stock thereto,

In the disintegrator, as shove stated, the required amount of Water is mixed with. the stock, the Water being heated hefore or after it is charged into the tanlrto eiieet disintegration of the reducible material therein, reduction of the material being further aided by the operation of the device. The increment oi the material from the endless carrier A to the sitter B and from the sitter to and through. the disintegrater C tot-he settling trough is, ferahly, continuous. However, in niodiued forms or construction means may he provided to interrupt the movement of the material at the point of discharge of any of the devices it, .l and C.

In the settling trough i) the nutter-int is further charged with Water troni the pump G, the mess of material flowing through the trough slowly to the Whirlpool D. During this movement oiithe material heavy foreign substances, such metals, glass, rocks, etc, Will become separated from the mass by equipped. As a result of this movement light foreign substances, which may not be reduced or used for pulp, will rise to the surface of the mass and may be skimmed off and removed therefrom.

From the Whirl-pool the stock flows continuouslyinto the beater E where it is subjected to constant grinding which acts to reduce both the fibrous and non-fibrous materials until theyentire mass is line enoughto pass through the backfall plate 11, into an overflow box E and thence into the thickener F. i

In the thickener or extractor F the mate rial engages the rotating cylinder mold 13 in a thin layer, and is carried up by the cylinder under the couch roll lei which acts to press the greater portion of the water from the pulp. The material is scraped off the couch roll by a scraper 15 and is delivered into a hopper 16. From the hopper the material may be transferred in any suitable manner to 0. stuff chest for the finished pulp. The water from the thickener flows into the pump G and is thence returned to the settling trough.

From the vfliregoing detailed description and accompanying drawings, the construction, operation and results-of operation ofthe apparatus will be readily understood by those experienced in the art of pulp production. It will be observed that the construction and operation of the apparatus is in efiect a continuous system of reduction.

It will be understood that the respective units of the apparatus may be arran ed at different elevations relative to each 0t er to efiect the desired movements of the material from one unit to another.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a reducing apparatus for making pulp, the combination of a sitter and means to deliver raw stock thereto, a disintegrator in series with the Sifter and adapted to re- .ceive the stock therefrom, and means comprising a. settling trough, a finishing beaten into which said trough delivers its whole, fioatable contents, and a thickener into which said finishing beater delivers reduced matcrial, all arranged in series with said' disintegrator and cooperatingtherewith to effect. reduction of said stock.
